WinSpice is a port of Spice3F4 to Win32 systems. WinSpice is ported to run in a window as a native 32-bit application. It can generate waveform plots to individual floating windows and contains a powerful scripting language (see the example files included with the executable).
WinSpice contains several enhancements over the original Berkeley Spice3F4:-
v1.6 [Apr 22, 2008]
Fixed a problem with lines like:-
v1 1 0 ac 1 sin
The dangling 'sin' causes no memory to be allocated for sin() function and this causes a crash. Fixed by always allocating some storage even if no parameters are given.
